Well, depends on what kind of monitoring you want. You could check the
deamon/service was running, but this does not show that it is actually
binding to a port. You could [as suggested] use netstat [or lsof] output to
check if a port was listed as "listening".
IIRC the monitoring is done this way to check that sensible data can be
fetched from the service so that a near certain "it's working, look I got
data!" style test can be performed.
